SAFETY & WARNING INFORMATION
OPERATING YOUR POLYESTER SYSTEM SAFELY
1. Introduction
Any tool, if used improperly, can be dangerous. Safety is ultimately the responsibility of those
using the tool. In like manner, safe operation of polyester processes is the responsibility of those
who use such processes and those who operate the equipment. This manual outlines
procedures to be followed in conducting polyester operations safety. This system has been
specifically designed for use of Polyester Resin, Gel-Coat, and Methyl Ethyl Ketone Peroxides
(MEKP) applications. Other formulations or blends considered for use in this equipment is
strictly prohibited without the expressed consent by Magnum Venus Plastech Inc. Magnum
Venus Plastech cannot eliminate every danger nor foresee every circumstance that might cause
an injury during equipment operation. Some risks, such as the high pressure liquid stream that
exits the spray tip, are inherent to the nature of the machine operation and are necessary to the
process in order to manufacture the end-product. For this reason, ALL personnel involved in
polyester operations should read and understand the Safety Manual. It is very important for the
safety of employees involved in the operation that equipment operators, maintenance and
supervisory personnel understand the requirements for safe operation. Each user should
examine his own operation, develop his own safety program and be assured that his equipment
operators follow correct procedures. Magnum Venus Plastech hopes that this manual is helpful
to the user and recommends that the precautions in this manual be included in any such
program. Magnum Venus Plastech recommends this Safety Manual remain on your equipment
at all times for your personnel safety. In addition to the manual, Magnum Venus Plastech
recommends that the user consult the regulations established under the Occupational Safety &
Health Act (OSHA), particularly the following sections:
1910.94 Pertaining to Ventilation.
1910.106 Pertaining to flammable liquids
1910.107 Pertaining to spray finishing operations, particularly Paragraph (m) Organic Peroxides
and Dual Component Coatings.
Other standards and recognized authorities to consult are the National Fire Protection
Association (NFPA) bulletins as follows:

1.2 Personal Safety Equipment
Magnum Venus Plastech recommends the following Personal Safety Equipment for conducting
safe operations of the Polyester Systems:
Magnum Venus Plastech recommends that the user consult the state and local regulations
established for all Safety equipment listed.
2.0 Material Safety
2.1 Hazards Associated with Laminating Operations
The major hazards which should be guarded against in polyester laminating operations are
those associated with:
1. The flammability and explosion dangers of the catalyst normally used – Methyl Ethyl Ketone
Peroxide (MEKP).
2. The flammability dangers of clean-up solvents sometimes used (Magnum Venus Plastech
recommends that clean-up solvents be non-flammable), and of resin diluents used, such as
styrene.
3. The flammability dangers of catalyst diluents, if used. (Magnum Venus Plastech recommends
that catalyst not be diluted.
4. The flammability dangers of the uncured liquid resins used.
5. The combustibility dangers of the cured laminate, accumulations of over spray, and laminate
sandings.
6. The toxicity dangers of all the chemicals used in laminating operations with respect to
ingestion, inhalation and skin and eye hazards.
Rev. 05/2012
Page | 7
PCP-2000 Catalyst Pump Manual
2.2 Catalyst (Methyl Ethyl Ketone Peroxide)
MEKP is among the more hazardous materials found in commercial channels. The safe
handling of the “unstable (reactive)” chemicals presents a definite challenge to the plastics
industry. The highly reactive property which makes MEKP valuable to the plastics industry in
producing the curing reaction of polyester resins also produces the hazards which require great
care and caution in its storage, transportation, handling, processing and disposal. MEKP is a
single chemical. Various polymeric forms may exist which are more or less hazardous with
respect to each other. These differences may arise not only from different molecular structures
(all are, nevertheless, called “MEKP”) and from possible trace impurities left from the
manufacture of the chemicals, but may also arise by contamination of MEKP with other
materials in its storage or use. Even a small amount of contamination with acetone, for instance,
may produce an extremely shock-sensitive and explosive compound.
Contamination with promoters or materials containing promoters, such as laminate
sandings, or with any readily oxidizing material, such as brass or iron, will cause
exothermic “redox” reactions which can become explosive in nature. Heat applied to
MEKP, or heat build-up from contamination reactions can cause it to reach what is called
its Self-Accelerating Decomposition Temperature (SADT).
Researchers have reported measuring pressure rates-of-rise well in excess of 100,000 psi per
second when certain MEKP’s reach their SADT. (For comparison, the highest pressure rate-ofrise listed in NFPA Bulletin NO.68, “Explosion Venting”, is 12,000 psi per second for an
explosion of 12% acetylene and air. The maximum value listed for a hydrogen explosion is
10,000 psi per second. Some forms of MEKP, if allowed to reach their SADT, will burst even an
open topped container. This suggests that it is not possible to design a relief valve to vent this
order of magnitude of pressure rate-of-rise. The user should be aware that any closed
container, be it a pressure vessel, surge chamber, or pressure accumulator, could explode
under certain conditions. There is no engineering substitute for care by the user in handling
organic peroxide catalysts. If, at any time, the pressure relieve valve on top of the catalyst tank
should vent, the area should be evacuated at once and the fire department called. The venting
could be the first indication of a heat, and therefore, pressure build-up that could eventually lead
to an explosion. Moreover, if a catalyst tank is sufficiently full when the pressure relief valve
vents, some catalyst may spray out, which could cause eye injury. For this reason, and many
others, anyone whose job puts them in an area where this vented spray might go, should
always wear full eye protection even when laminating operations are not taking place.
Safety in handling MEKP depends to a great extent on employee education, proper safety
instructions and safe use of the chemicals and equipment. Workers should be thoroughly
informed of the hazards that may result from improper handling of MEKP, especially in regards
to contamination, heat, friction and impact. They should be thoroughly instructed regarding the
proper action to be taken in the storage, use and disposal of MEKP and other hazardous
materials used in the laminating operation. In addition, users should make every effort to:
A. Store MEKP in a cool, dry place in original containers away from direct sunlight and away
from other chemicals.
B. Keep MEKP away from heat, sparks and open flames.
C. Prevent contamination of MEKP with other materials, including polyester over spray and
sandings, polymerization accelerators and promoters, brass, aluminum and non-stainless
steels.
Rev. 05/2012
Page | 8
PCP-2000 Catalyst Pump Manual
D. Never add MEKP to anything that is hot, since explosive decomposition may result.
E. Avoid contact with skin, eyes and clothing. Protective equipment should be worn at all times.
During clean-up of spilled MEKP, personal safety equipment, gloves and eye protection must be
worn. Firefighting equipment should be at hand and ready.
F. Avoid spillage, which can heat up to the point of self-ignition.
G. Repair any leaks discovered in the catalyst system immediately, and clean up the leaked
catalyst at once in accordance with the catalyst manufacturer’s instructions.
H. Use only original equipment or equivalent parts from Magnum Venus Plastech in the catalyst
system (i.e.: hoses, fitting, etc.) because a dangerous chemical reaction may result between
substituted parts and MEKP.
I. Catalyst accumulated from the purging of hoses or the measurement of fluid output deliveries
should never be returned to the supply tank, such catalyst should be diluted with copious
quantities of clean water and disposed of in accordance with the catalyst manufacturer’s
instructions.
The extent to which the user is successful in accomplishing these ends and any additional
recommendations by the catalyst manufacturer determines largely the safety that will be present
in his operation.
2.3 Clean-Up Solvents and Resin Diluents
WARNING
A hazardous situation may be present in your pressurized fluid system! Hydrocarbon
Solvents can cause an explosion when used with aluminum or galvanized components in
a closed (pressurized) fluid system (pump, heaters, filters, valves, spray guns, tanks,
etc.). The explosion could cause serious injury, death and/or substantial property
damage. Cleaning agents, coatings, paints, etc. may contain Halogenated Hydrocarbon
Solvents. Some Magnum Venus Plastech spray equipment includes aluminum or
galvanized components and will be affected by Halogenated Hydrocarbon Solvents.
A. There are three key elements to the Halogenated Hydrocarbon (HHC) solvent hazard.
a. The presence of HHC solvents. 1,1,1 – Trichloroethane and Methylene Chloride are
the most common of these solvents. However, other HHC solvents are suspect if
used; either as part of paint or adhesives formulation, or for clean-up flushing. b.
Aluminum or Galvanized Parts. Most handling equipment contains these elements. In
contact with these metals, HHC solvents could generate a corrosive reaction of a
catalytic nature.
b. Equipment capable of withstanding pressure. When HHC solvent contact aluminum or
galvanized parts inside a closed container such as a pump, spray gun, or fluid
handling system, the chemical reaction can, over time, result in a build-up of heat and
pressure, which can reach explosive proportions.
When all three elements are present, the result can be an extremely violent explosion. The
reaction can be sustained with very little aluminum or galvanized metal; any amount of
aluminum is too much.
Rev. 05/2012
Page | 9
PCP-2000 Catalyst Pump Manual
A. The reaction is unpredictable. Prior use of an HHC solvent without incident (corrosion or
explosion) does NOT mean that such use is safe. These solvents can be dangerous alone (as a
clean-up or flushing agent) or when used as a component or a coating material. There is no
known inhibitor that is effective under all circumstances. Furthermore, the mixing of HHC
solvents with other materials or solvents, such as MEKP, alcohol, and toluene, may render the
inhibitors ineffective.
B. The use of reclaimed solvents is particularly hazardous. Reclaimers may not add any
inhibitors. Also, the possible presence of water in reclaimed solvents could feed the reaction.
C. Anodized or other oxide coatings cannot be relied upon to prevent the explosive reaction.
Such coatings can be worn, cracked, scratched, or too thin to prevent contact. There is no
known way to make oxide coatings or to employ aluminum alloys, which will safely prevent the
chemical reaction under all circumstances.
D. Several solvent suppliers have recently begun promoting HHC solvents for use in coating
systems. The increasing use of HHC solvents is increasing the risk. Because of their exemption
from many State Implementation Plans as Volatile Organic Compounds
(VOC’s), their low flammability hazard, and their not being classified as toxic or carcinogenic
substances, HHC solvents are very desirable in many respects.
WARNING: Do not use Halogenated Hydrocarbon solvents in pressurized fluid systems
having aluminum or galvanized wetted parts.
NOTE: Magnum Venus Plastech is aware of NO stabilizers available to prevent
Halogenated Hydrocarbon solvents from reaction under all conditions with aluminum
components in closed fluid system.
TAKE IMMEDIATE ACTION… Halogenated
Hydrocarbon solvents are dangerous when used with aluminum components in a closed
fluid system.
A. Consult your material supplier to determine whether your solvent or coating contains
Halogenated Hydrocarbon Solvents.
B. Magnum Venus Plastech recommends that you contact your solvent supplier regarding the
best non-flammable clean-up solvent with the heat toxicity for your application.
C. If, however, you find it necessary to use flammable solvents, they must be kept in approved,
electrically grounded containers.
D. Bulk solvent should be stored in a well-ventilated, separate building, 50 feet away from your
main plant.
E. You should allow only enough solvent for one day’s use in your laminating area.
F. “NO SMOKING” signs must be posted and observed in all areas of storage or where solvents
and other flammable materials are used.
G. Adequate ventilation (as covered in OSHA Section 1910.94 and NFPA No.91) is important
wherever solvents are stored or used, to minimize, confine and exhaust the solvent vapors.
H. Solvents should be handled in accordance with OSHA Section 1910.106 and 1910.107.

2.4 Catalyst Diluents
Magnum Venus Plastech spray-up and gel-coat systems currently produced are designed so
that catalyst diluents are not required. Magnum Venus Plastech, therefore, recommends that
diluents not be used. This avoids the possible contamination which could lead to an explosion
due to the handling and mixing of MEKP and diluents. In addition, it eliminates any problems
from the diluents being contaminated through rust particles in drums, poor quality control on the
part of the diluent suppliers, or any other reason. If, however, diluents are absolutely required,
contact your catalyst supplier and follow his instructions explicitly. Preferable, the supplier
should premix the catalyst to prevent possible “on the job” contamination while mixing.
WARNING
If diluents are not used, it should be remembered that catalyst spillage, gun, hose and
packing leaks are potentially more hazardous, since each drop contains a higher
concentration of catalyst, and therefore will react quicker with over spray and the leak.
2.5 Cured Laminate, Overspray and Laminate Sandings Accumulation
A. Remove all accumulations of overspray, FRP sandings, etc. from the building as they occur.
If this waste is allowed to build up, spillage of catalyst is more likely to start a fire, in addition, the
fire would burn hotter and longer.
B. Floor coverings, if used, should be non-combustible.
C. Spilled or leaked catalyst may cause a fire if it comes in contact with an FRP product, oversprayed chop or resin, FRP sandings or any other material with MEKP.
To prevent this spillage and leakage, you should:
1. Maintain your Magnum Venus Plastech System. Check the gun several times daily for
catalyst and resin packing or valve leaks. REPAIR ALL LEAKS IMMEDIATELY.
2. Never leave the gun hanging over, or lying inside the mold. A catalyst leak in this situation
would certainly damage the part, possibly the mold, and may cause a fire.
3. Inspect resin and catalyst hoses daily for wear or stress at the entry and exits of the boom
sections and at the hose and fittings. Replace if wear or weakness is evident or suspected.
4. Arrange the hoses and fiberglass roving guides so that the fiberglass strands DO NOT rub
against any of the hoses at any point. If allowed to rub, the hose will be cut through, causing a
hazardous leakage of material which could increase the danger of fire. Also, the material may
spew onto personnel in the area.
2.7 Toxicity of Chemicals
A. Magnum Venus Plastech recommends that you consult OSHA Sections 1910.94, 1910.106,
1910.107 and NFPA No.33, Chapter 14, and NFPA No.91.
B. Contact your chemical supplier(s) and determine the toxicity of the various chemicals used as
well as the best methods to prevent injury, irritation and danger to personnel.
C. Also determine the best methods of first aid treatment for each chemical used in your plant.
Rev. 05/2012
Page | 11
PCP-2000 Catalyst Pump Manual
2.8 Treatment of Chemical Injuries
Great care should be used in handling the chemicals (resins, catalyst and solvents) used in
polyester systems. Such chemicals should be treated as if they hurt your skin and eyes and as if
they are poison to your body. For this reason, Magnum Venus Plastech recommends the use of
protective clothing and eye wear in using polyester systems. However, users should be
prepared in the event of such an injury. Precautions include:
1.
Know precisely what chemicals you are using and obtain information from your chemical
supplier on what to do in the event the chemical gets onto your skin or into the eyes, or is
swallowed.
2.
Keep this information together and easily available so that it may be used by those
administering first aid or treating the injured person.
3.
Be sure the information from your chemical supplier includes instructions on how to treat
any toxic effects the chemicals have.
WARNING
Contact your doctor immediately in the event of any injury and give him the information
you have collected. If your information includes first aid instructions, administer first aid
immediately while you are contacting your doctor.
Fast treatment of the outer skin and eyes that contact such chemicals generally includes
immediate and thorough washing of the exposed skin and immediate and continuous flushing of
the eyes with lots of clean water for at least 15 minutes or more. These general instructions of
first aid treatment, however, may be incorrect for some chemicals; that is why you must know
the chemicals and treatment before an accident occurs. Treatment for swallowing a chemical
frequently depends upon the nature of the chemical.
NOTE: Refer to your System User Manual for complete and detailed operating
instructions and service information.
Rev. 05/2012

3.0 Equipment Safety
WARNING
Magnum Venus Plastech suggests that personal safety equipment such as EYE
GOGGLES, GLOVES, EAR PROTECTION, and RESPIRATORS be worn when servicing or
operating this equipment. Ear protection should be worn when operating a fiberglass
chopper to protect against hearing loss since noise levels can be as high as 116 dB
(decibels). This equipment should only be operated or serviced by technically trained
personnel!
WARNING
Never place fingers, hands, or any body part near or directly in front of the spray gun
fluid tip. The force of the liquid as it exits the spray tip can cause serious injury by
shooting liquid through the skin. NEVER LOOK DIRECTLY INTO THE GUN SPRAY TIP OR
POINT THE GUN AT OR NEAR ANOTHER PERSON. (TREAT THE GUN AS IF IT WERE A
LOADED PISTOL.)
3.1 Emergency Stop Procedures
The following steps should be followed in order to stop the machinery in an emergency situation
1. The ball valve located where the air enters the power head of the resin pump, should be
moved to the “OFF” or closed position. To do this, simply rotate the lever on the ball valve
90 degrees. Doing this will cause all the system air to bleed out of the system in a matter of
a few seconds, making the system incapable of operating
NOTE: Step 2 is a precautionary step and should be followed whenever the above
mentioned ball valve is activated to the stop mode. Failure to do so, can damage the
regulators and components on reactivating to the “ON” position.
2. Turn all system regulators to the “OFF” position (counter-clockwise) position
NOTE: Verify that the Catalyst relief line, located on the catalyst manifold, and the resin
return line, located on the resin filter, are secured relieving catalyst and resin fluid
pressure.
3. Catalyst pressure in the catalyst pump can be eliminated by rotating the ball valve on the
catalyst manifold 90 degrees to the “open” or “on” position.
Note: The “open” or “on” position is when the ball valve handle is parallel (in line) with
the ball valve body. The “closed” or “off” position is when the ball valve handle is
perpendicular (across) the ball valve body.
4. Resin pressure in the resin pump can be eliminated by rotating the ball valve on the resin
filter 90 degrees to the “open” or “on” position. Place a container under the ball valve to
catch any resin that is ejected out of the valve.

3.2 Grounding
Grounding an object means providing an adequate path for the flow of the electrical charge from
the object to the ground. An adequate path is one that permits charge to flow from the object fast
enough that it will not accumulate to the extent that a spark can be formed. It is not possible to
define exactly what will be an adequate path under all conditions since it depends on many
variables. In any event, the grounding means should have the lowest possible electrical
resistance. Grounding straps should be installed on all loose conductive objects in the spraying
area. This includes material containers and equipment. Magnum Venus Plastech recommends
grounding straps be made of AWG No.18 stranded wire as a minimum and the larger wire be used
where possible. NFPA Bulletin No77 states that the electrical resistance of such a leakage path
may be as low as 1 meg ohm (10 ohms) but that resistance as high as 10,000 meg ohms will
produce an adequate leakage path in some cases. Whenever flammable or combustible liquids
are transferred from one container to another, or from one container to the equipment, both
containers or container and equipment shall be effectively bonded and grounded to dissipate static
electricity. For further information, see National Fire Protection Association ( NFPA) 77, titled
“Recommended Practice on Static Electrical”. Refer especially to section 7-7 titled “Spray
Application of Flammable and Combustible Materials”. Check with local codes and authorities for
other specific standards that might apply to your application. NEVER USE HARD MATERIALS
SUCH AS WIRE, PINS, ETC., TO CLEAR A PLUGGED GUN. HARD MATERIALS CAN CAUSE
PERMANENT DAMAGE. DAB WITH A BRISTLE BRUSH, BLOW BACKWARDS WITH AIR UNTIL
CLEAR WHILE WEARING A PROTECTIVE EYE SHIELD. REPEAT AS MANY TIMES AS
NECESSARY. DO NOT PERFORM ANY MAINTENANCE OR REPAIRS UNTIL YOU HAVE
FOLLOWED THE PRECAUTIONS STATED ABOVE. IF YOU, AS AN EQUIPMENT OPERATOR
OR SUPERVISOR, DO NOT FEEL THAT YOU HAVE BEEN ADEQUATELY TRAINED OR
INSTRUCTED AND THAT YOU LACK THE TECHNICAL KNOWLEDGE TO OPERATE OR
PERFORM MAINTENANCE ON A PIECE OF MAGNUM VENUS PLASTECH EQUIPMENT,
PLEASE CALL MAGNUM VENUS PLASTECH BEFORE OPERATING OR PERFORMING
MAINTENANCE ON THE EQUIPMENT. IF YOU HAVE ANY QUESTIONS REGARDING THE
ABOVE PRECAUTIONS OR ANY SERVICE OR OPERATION PRECEDURES, CALL YOUR
MAGNUM VENUS PLASTECH DISTRIBUTOR OR MAGNUM VENUS PLASTECH.
NOTICE: All statements, information and data given herein are believed to be accurate and
reliable but are presented without guaranty, warranty or responsibility of any kind express
or implied. The user should not assume that all safety measures are indicated or that other
measures are not required.
DANGER: Contaminated catalyst may cause Fire or Explosion. Before working on the
catalyst pump or catalyst accumulator, wash hands and tools thoroughly. Be sure work
area is free of dirt, grease or resin. Clean catalyst system components with clean water
only.
DANGER: Eye, skin and respiration hazard. The Catalyst, MEKP, may cause blindness,
skin irritation or breathing difficulty. Keep hands away from face. Keep food and drink
away from work area.

Maintenance
 At least every six months, completely disassemble and inspect the catalyst pump
assembly. Replace the S.S. balls, O-Rings, springs, piston seal and packing
assembly.

Snug / tighten the Metering pump packing nut approximately 1/8 – 1/4 turn
clockwise to prevent leakage. Repeat this procedure when necessary to
prevent material from leaking. Do not over tighten as this will reduce the
life of the packing set and may cause damage to the pump.
Troubleshooting
 The catalyst system should be checked if you are experiencing an uneven cure
or slow gel time.
 For a complete troubleshooting guide, please refer to the manual “Testing &
Adjusting Your MVP Pumping System” containing important testing procedures
that should be performed every time the catalyst pump is serviced.

Remove Catalyst Pump Assembly:
CAUTION: There are four (4) small stainless steel balls in the catalyst pump assembly. If
a ball drops to the floor, it will be damaged. (Even if it appears undamaged, it will contain
dents and scratches that will create problems.) Damaged balls must be replaced or the
pump will not work properly.
WARNING: Be sure hands, tools and work area are clean and free of resin, dirt or grease
before attempting to disassemble the components of the catalyst pump assembly.
DANGER: To prevent injury, never perform service and repair on the catalyst system
until system pressure has been relieved.
DANGER: If material is plugging the system, some parts of the system may still contain
fluids under high pressure, even after following normal procedures to relieve pressure.
1. Turn Pump Pressure regulator to zero (0) psi.
2. Relieve fluid pressure by opening recirculation valve on the catalyst manifold. For
system without a catalyst manifold hold the gun over an appropriate container and pull
the trigger.
3. Drain any remaining catalyst from the catalyst jug.
WARNING: Follow catalyst manufacturer’s recommendations regarding handling,
storage or disposal of catalyst.
WARNING: To prevent injury, hold a large rag or shop towel around the wrench and
fitting as you remove the fitting. Remove fitting slowly to allow fluid pressure to escape
into the rag or towel.
4. Read the warning above, then disconnect hose lines and cover them so they do not leak.
5. Remove the catalyst pump assembly from the slave arms by removing the priming knob
(50100-1), and upper and lower quick pins (52106-3).
